Original article, December 10, 2019 (9PM ET): India’s largest integrated telecommunications company, Airtel, just announced it’s launching the country’s first voice over Wi-Fi service. The company is calling it Airtel Wi-Fi Calling, and it’s available in Delhi NCR and will gradually roll out across the country.

Voice over Wi-Fi is something we have had in the US for many years now. Sprint began offering the service way back in 2014, and the other major carriers followed soon after.

Wi-Fi calling is so convenient because it allows users to make and receive calls over Wi-Fi even if they don’t have a signal. And unlike services like Skype, FaceTime, or Duo, Wi-Fi calling lets you use your existing phone number without needing to download a separate app.

Airtel Wi-Fi Calling works in this same way, and users can set it up by following these steps:

How to use Airtel Wi-Fi Calling?

  • Check if your smartphone is compatible with the service at airtel.in/wifi-calling. Some devices include the OnePlus 7T, Xiaomi Pocophone F1, and Samsung Galaxy J6.
  • Upgrade your device to its latest firmware version.
  • On your device, navigate to your settings to switch on Wi-Fi calling.
  • Don’t turn off VoLTE so your device can seamlessly transition between standard and Wi-Fi Calling.

It’s as simple as that. Once you have gone through those steps, you are all set. Your device should now support voice over Wi-Fi.

Airtel is currently working with many leading smartphone manufacturers to implement voice over Wi-Fi. So, if your smartphone isn’t compatible yet, check back periodically to see the company’s updated supported devices list.
